Practice Python Exercise 1

#### Create a program that asks the user to enter their name and their age. Print out a message addressed to them that tells them the year that they will turn 100 years old.

Extras:

Add on to the previous program by asking the user for another number and printing out that many copies of the previous message. (Hint: order of operations exists in Python)

Print out that many copies of the previous message on separate lines. (Hint: the string "\n is the same as pressing the ENTER button)

#Version 1
def main():
    name, age = input("Enter name") , int( input("Enter age"))
    for i in range( int(input("Enter a number"))):
         print("You will turn 100 in {}".format(2017-age+100))
main()









    



Enter nameVipin
Enter age27
Enter a number2
You will turn 100 in 2090
You will turn 100 in 2090

Using datetime module to find current date and extracting year from the current date



In [ ]:

    
from datetime import date 
today = str(date.today()).split("-")
print(type(today))
print(today[0])

Use the above and modify our program
